What are the safety requirements for automotive interior materials?

The safety performance evaluation indicators of automobile interior materials mainly include air pollutant content, atomization, flame retardancy, etc. [Standard Group] engineers said that there are different standards for different indicators of these safety tests.

Pollutant content of car interior air:

Depending on the source of the pollutants, non-metallic materials, parts and vehicles are tested for detection of atmospheric pollutants. There are three main categories of tests for air pollutants in cars: odor assessment, which relies primarily on the human sense of smell for quality assessment (VDA270), and electronic nose measurement (SAEJ351) can also be used; quantitative analysis of volatile organic pollutants (COV), including top Air chromatography, thermal desorption method, high performance liquid chromatography, etc. ; For the determination of carbon and nitrogen oxide content, the non-persive infrared gas determination method (GB/T28370) can be used.

At present, relevant standards have been issued for whole-vehicle VOC detection in China, but there are no relevant standards for detection of VOCs in non-metallic parts. . Detection methods are not uniform.

Parts and materials testing standards include: ISO12219, VDA270, DIN13130, DINEN13725, VDA275, VDA277, VDA278, SAEJ351 and many other standards.

The test method and limit requirements for organic pollutants of the whole vehicle are mainly tested and evaluated according to national standards HJ/T400-2007 and GB /T27630-2011.

Atomization:

By performing atomization tests on automotive interior decoration materials, the control of volatile substances in these materials is effectively achieved. It has become an important aspect of the means by which manufacturers of automobiles and automobile interior materials can control product quality in order to reduce environmental pollution inside the car.

At present, fog test methods for automobile interior materials include gravimetric method, gloss method and haze method. Their principles of nebulization are the same and they all use the volatilization of substances. - The principle of condensation to achieve the process of nebulization, the difference is that the measured parameters are condensation components, nebulization value or mist.

Standards to which reference can be made includent German standard DIN75201, American standard SAEJ1756, ASTM D5393, British standard BS EN14288 and international standard ISO 6452.

Flame retardant:

The Flame retardancy test involves retarding the flame retardancy of the tested object. Test methods for ability to continue, spread and propagate. After years of development, flame retardancy testing has given rise to various standards and has become a very important testing item in related industries. Most of the combustion pe Performance tests of vehicle interior materials require the test materials to be subjected to different sources of fire in harsh test environments using fire sources specified by the standards, and then the phenomena combustion of materials are observed and evaluated.

The flame retardancy test can refer to the following standards: GB8410-2006, DIN75200, ISO3795, ASTMD5132, FMVSS302, JISD1201, UL94, etc.
